Step-by-step explanation:
I can't see the choices but it would be something like
y= -1/5x + ...
explanation: a perpendicular line would have a negative reciprocol slope.
Question 1. 7:11
Question 2. 27 units of K
How to solve the questions-
1. 14/22 divide the numerator and the denominator by 2. This would give you 7/11
2. If the ratio is 12/9 and the amount of N is 36, you’re basically multiplying 12 *3, so then you have to multiply 9 *3=27.
You can divide everything by “4” which would end up with the answer being
5-2x over 1 which would be just 5-2x
